For solvents heavier than water chloroform dichloromethane and othersContinuous extraction is achieved when fresh solvent dripping (refluxing) from condenser B travels through the aqueous phase (upper layer) in extractor G. As the solvent collects at the bottom of the extractor and reaches the level of tube E it is siphoned automatically through the open PTFE stopcock D into a heated solvent reservoir attached at C.ProcedureWith PTFE stopcock D closed transfer a volume of solvent to the extractor to about the level of the stopcock. Carefully add the aqueous material making sure it does not run out the sidearm. Clamp the extractor onto a rack and attach a suitable flask half-full of solvent at C. The flask should be equipped with boiling chips or a magnetic stirring bar and a source of heat. Open stopcock D and slowly add solvent to the extractor until excess runs over to the flasks via return tube E. Attach a reflux condenser at B and apply heat to the flasks so that rapid reflux i
